Temporal bone fractures can occur after severe blunt trauma to the head and sometimes involve structures of the ear, causing hearing loss, vertigo, balance disturbance, or facial paralysis. Temporal bone CT is an excellent technique for the diagnosis of acute coalescent mastoiditis, by demonstrating the air cell septa breakdown, the breakthrough of the sigmoid bony plate, and the lateral cortical wall of the mastoid. Fig. 80% to 90% of cases with temporal bone trauma sustain unilateral injury [ 1 - 3 ]. While most fractures heal without permanent injury, there are several complications that can occur with broken bones. The temporal bones are overlaid by the sides of the head known as the temples, and house the structures of the ears. 1 ). 1 and 2). You may have to wear a cast or splint to prevent further damage. Temporal bone fractures can potentially cause complications including hearing loss, dizziness, facial paralysis, or leaking of cerebrospinal fluid (CSF). Temporal Bone Fractures.

S02.81XA is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. This can lead to a number of serious complications, including damage to hearing, vertigo, facial paralysis (due to damage to the facial nerve), and bleeding in the ear as well as bone bruising. By reference to the long axis of the petrous temporal bone (ie in the plane of the ear canal), 80% of temporal bone fractures are longitudinal (from lateral blows) and 20% . The petrous part of the temporal bone is pyramid-shaped and is wedged in at the base of the skull between the sphenoid and occipital bones.Directed medially, forward, and a little upward, it presents a base, an apex, three surfaces, and three angles, and houses in its interior, the components of the inner ear.The petrous portion is among the most basal elements of the skull and forms part of . Ossicular disruption occurred in 17 (37.0%). Using this plane, fractures may be classified as follows: longitudinal fractures transverse fractures mixed fractures Otic capsule involvement There are three different types of temporal bone fractures: This fracture occurs in the temporoparietal region of the skull. As the bone remains aligned after the blow, it is usually easier to treat a non-displaced fracture as compared to a displaced fracture. Purpose To assess the repeatability of apparent diffusion coefficient (ADC) estimates in extracranial soft-tissue diffusion-weighted magnetic resonance imaging across a wide range of imaging protocols and patient populations. Your doctor may give you pain relief medications to help reduce swelling. Temporal Bone Fracture Knowing that the temporal bone is close to so many important structures and plays a role in speech, swallowing, hearing, balance, fluid drainage, nerve pathways, and protection of the brain, it is obvious that a fracture in this region can cause serious damage. A temporal bone fracture generally requires very strong forces to the skull that occur either laterally or in an anterior or posterior ear direction.
